-EC2, Hadoop, copy file from CLUSTER_MASTER to CLUSTER, failing
Saptarshi Guha 2009-06-20, 06:09
I have a cluster with 1 master and 1 slave (testing). In the EC2
scripts, in the hadoop-ec2-init-remote.sh file, I wish to copy a file
the MASTER to the CLUSTER i.e in the slave section
scp $MASTER_HOST:/tmp/v /tmp/v
However, this didnt work and when I logged in, ssh'd to the slave and
tried the command, I got the following error:
Permission denied (publickey,gssapi-with-mic)
Yet, the group permissions appear to be valid i.e
ec2-authorize $CLUSTER_MASTER -o $CLUSTER -u $AWS_ACCOUNT_ID
ec2-authorize $CLUSTER -o $CLUSTER_MASTER -u $AWS_ACCOUNT_ID
So I don't see why I can't ssh into the MASTER group from a slave.
Any suggestion as to where I'm going wrong?
P.S I know I can copy a file from S3, but would like to know what is
going on here.
